Responde el siguiente problema de lógica: Al mirar el reloj, vemos que la manecilla de los minutos apunta a un número que casual
ANTONII [103]

Answer: 11:50

Step-by-step explanation:

Ok, la manecilla de los minutos apunta al numero X.

si la ora es Y, entonces Y + X = 12:00

podemos asumir que Y es 11:y

y es la cantidad de minutos despues de las 11, es un numero entre 0 y 59 (por que una hora solo puede tener 60 minutos)

Si la manecilla de los minutos apunta al numero 6 por ejemplo, entoces:

y = 11:30 y X = 6 min

X + y = 11:30 + 0:06 = 11:36

Así funciona.

la equacion es:

y = 5*X

y tambien queremos que:

X + y = 60min

reemplazo y por lo de la equacion de arriba:

X + y = X + 5*X = 6X = 60min

X = 10

Si la manecilla apunta al 10, tenemos que:

y = 11:50 y X = 10min

y + X = 11:50 + 0:10 = 12:00

Entonces podemos concluir que la hora es 11:50.

sveticcg [70]

9514 1404 393

Answer:

  4 1/6 miles per hour

Step-by-step explanation:

6 minutes is 1/10 hour, so Sara's speed is ...

  speed = distance/time

  speed = (5/12 mi)/(1/10 h) = 50/12 mi/h

  speed = 4 1/6 mi/h

Sara's speed is 4 1/6 miles per hour.

When viewed from the front, the rope used to tie down a tent forms a pair of supplementary angles with the ground. Find m abc​
DedPeter [7]

Supplementary angles are angles that add up to 180 degrees.

180 = 3x + 4 + 8x + 11

Combine like terms.

180 = 11x + 15

Subtract 15 from both sides.

165 = 11x

Divide both sides by 11

15 = x

m<ABC = 3x + 4 = 3(15) + 4 = 45 + 4 = 49 degrees.
